“…One manganite, in particular, La 0.67 Sr 0.33 MnO 3 (LSMO), has attracted much attention due to its high Curie temperature of 360 K. Using pulsed laser deposition (PLD), epitaxial thin films of LSMO can be grown with minimal oxygen vacancies. 15 Thickness-dependent thin film studies in LSMO led to new findings such as a shift in Curie temperature, [16][17][18] coexisting magnetic phases, 16,19 and the presence of magnetic dead layers. [20][21][22][23][24] In addition to controlling film thickness, the influence of strain induced by an underlying substrate 6 on the angle-dependent magnetotransport in LSMO thin films has been investigated.…”

Strain-engineering is used as a tool to alter electronic and magnetic properties like anisotropy energy. This study reports the different angledependent magnetoresistance properties of the strain-engineered La 0.67 Sr 0.33 MnO 3 (LSMO) thin films, grown on LaAlO 3 , compared to their bulk analogs. Upon increasing temperature, a symmetry change from fourfold [cos(4h)] to twofold [cos(2h)] is observed in the angledependent resistance measurements. This systematic study with increasing temperature allows us to define three distinct temperaturedependent phases. The fourfold symmetric signal originates from magnetocrystalline anisotropy, whereas the twofold symmetric signal is believed to be the conventional anisotropic magnetoresistance. Our observations show that strain-engineering creates the possibility to manipulate the anisotropy, which, for example, can ultimately lead to observations of noncollinear quasi-particles like skyrmions in single layer thin films of LSMO.

“…LFO is a typical AFM material (T N = 710 K) and has been applied in various systems with an EB effect [19,26,27], while LCMO is a widely studied FM material (Curie temperature T C = 225 K). [28] Therefore, the EB effect is expected in the LFO:LCMO composite thin film, and the H EB value can be tailored by varying the composition of the two phases.…”

Composite thin films arouse great interests owing to the multifunctionalities and heterointerface induced physical property tailoring. The exchange bias effect aroused from the ferromagnetic (FM)–antiferromagnetic (AFM) heterointerface is applicable in various applications such as magnetic storage. In this work, (LaFeO3)x:(La0.7Ca0.3MnO3)1−x composite thin films have been deposited via pulsed laser deposition (PLD) and the exchange bias effect was investigated. In such system, LaFeO3 (LFO) is an antiferromagnet while La0.7Ca0.3MnO3 (LCMO) is a ferromagnet, which results in the exchange bias interfacial coupling at the FM/AFM interface. The composition variation of the two phases could lead to the exchange bias field (HEB) tuning in the composite system. This work demonstrates a new composite thin film system with FM-AFM interfacial exchange coupling, which could be applied in various spintronic applications.

“…Due to the sensitivity of the material properties of LSMO to a variety of factors, the importance of growing high-quality films cannot be understated. Various methods are used to fabricate LSMO and other oxide films including molecular beam epitaxy 27 , chemical solution deposition 28 , and sputter deposition 29 . Another widely used technique is pulsed laser deposition (PLD).…”

Depth dependent atomic valence determination in La0.7Sr0.3MnO3 thin films using synchrotron techniques

Depth dependent atomic valence determination in La0.7Sr0.3MnO3 thin films using synchrotron techniques Robbyn Trappen The valence of atoms often has a strong effect on the properties of materials, such as magnetism, conductivity, and superconductivity. The atomic valence is often perturbed at the surface and/or interface and this deviation may play a strong role in many physical phenomena such as interfacial coupling and dead layers, both magnetic and electric. In this dissertation, I present a non-destructive approach of combining two X-ray absorption detection modes, electron yield and fluorescence, with very different probing depths in conjunction with theory to map out the layer-by-layer valence of a thin film.
