“…The apparent diffusion of Sr ions from the interface results in the low‐BE‐Sr species having a different local structural environment than in STO and this result holds the key to understanding the unusual BE of this feature. [ 64 ] A similar Sr 3 d shift to lower BE was also reported for STO overlayers on LAO/STO heterostructures [ 65 ] and for lanthanum strontium ferrite thin films on STO. [ 64 ] These shifts are influenced by band alignment across the heterostructure as effective band shifts affect the energies of all core‐levels.…”

Identifying Ionic and Electronic Charge Transfer at Oxide Heterointerfaces

et al. 2020

The ability to tailor oxide heterointerfaces has led to novel properties in low‐dimensional oxide systems. A fundamental understanding of these properties is based on the concept of electronic charge transfer. However, the electronic properties of oxide heterointerfaces crucially depend on their ionic constitution and defect structure: ionic charges contribute to charge transfer and screening at oxide interfaces, triggering a thermodynamic balance of ionic and electronic structures. Quantitative understanding of the electronic and ionic roles regarding charge‐transfer phenomena poses a central challenge. Here, the electronic and ionic structure is simultaneously investigated at the prototypical charge‐transfer heterointerface, LaAlO3/SrTiO3. Applying in situ photoemission spectroscopy under oxygen ambient, ionic and electronic charge transfer is deconvoluted in response to the oxygen atmosphere at elevated temperatures. In this way, both the rich and variable chemistry of complex oxides and the associated electronic properties are equally embraced. The interfacial electron gas is depleted through an ionic rearrangement in the strontium cation sublattice when oxygen is applied, resulting in an inverse and reversible balance between cation vacancies and electrons, while the mobility of ionic species is found to be considerably enhanced as compared to the bulk. Triggered by these ionic phenomena, the electronic transport and magnetic signature of the heterointerface are significantly altered.

“…In the general case of a classical Markovian N -level system, we derive the condition (34) with an arbitrary matrixĈ depending on q and on the protocol at one period, but not on the number of periods M to satisfy an infinite-time fluctuation theorem (17). Also we provide the sufficient condition (35) for the corresponding finitetime fluctuation theorem (15) posing additional restrictions on the initial distribution similarly to [57].…”

“…In most of these systems, thermodynamic variables (work, heat, or entropy) has been extracted indirectly via the measurement of the microscopic state of the system (a position of the bead in a laser tweezer, an instantaneous angular deflection of the rotation pendulum, a charge state of a Coulomb-blockaded device and so on). Direct measurements of the heat or work especially in quantum systems [27,28] have not been done yet, but many efforts have been undertaken, especially in the most stable Coulomb-blockaded devices [29,30,31,32,33,34].…”

In this paper, we address an important question of the relationship between fluctuation theorems for the dissipated work W d = W −∆F with general finitetime (like Jarzynski equality and Crooks relation) and infinite-time (like Gallavotti-Cohen theorem) drive protocols and their time-reversal symmetric versions. The relations between these kinds of fluctuation relations are uncovered based on the examples of a classical Markovian N -level system. Further consequences of these relations are discussed with respect to the possible experimental verifications.

“…It has been reported that the improvement of ΔT can be attributed to the increasing transformation fraction of the austenite phase under the larger stress. [15] Meanwhile, the ΔT reaches the maximum heating effect of 6.3 K under loading 400 MPa, which is higher than some eC materials like Ni 35 (6 K under 260 MPa) alloys. [17,38] In addition, the ΔT reaches -4.7 K during the unloading process.…”

“…[14] To improve the stability, some alternative solutions are proposed, such as introducing second-phase particles in grain boundaries, microalloying with boron or alloying with additional elements. [15,16] Recently, a reversible eC effect has been achieved in NiMnTi(Co) MSMAs by adding Co into ternary NiMnTi systems. [17] The materials belong to the all-d-metal Heusler alloys fully composed of transition metal (d-metal) elements.…”

The magnetocaloric effect and the elastocaloric effect in a polycrystalline all‐d‐metal Ni37Co9Fe4Mn35Ti15 magnetic shape memory alloy are investigated. The alloy undergoes a transition from ferromagnetic austenite to weak‐magnetic martensite near room temperature. It exhibits a maximum magnetic entropy change of 8.4 J Kg−1 K−1 under the magnetic field of 3 T. Moreover, a maximum temperature change of 6.3 K associated martensite transition is obtained at room temperature by loading the uniaxial stress of 400 MPa. These results suggest that the alloy is the promising candidate for new solid‐state refrigeration materials.
