“…In addition, whent he loaded compressive strain increased, the fitted parameter a also increased, which meanst hat the effect on the host medium outside the spherical particle was significant in the spherical CIPs/ rubber composite. While the valueo fc os 2 h increased monotonically with increase in loaded strain, the deflection angle of the flaky particles decreased and the orientation degree becamemuchmorenoticeable in the flaky CIPs/rubber composite, that is, the orientation effect on the permeability is consistent with otherresults [24].…”

Piezo-absorbing effect of microwave absorbing composites with carbonyl iron particles as the filler Anew piezo-absorbing composite was fabricated with silicone rubber and spherical or flaky carbonyl iron particles (CIPs). The complex permittivity and permeability of the composites, under variable compressive strain, werem easured using av ector network analyzer in the frequency of 2-18GHz and the reflection loss ( RL)c alculated to test the piezo-absorbing effect. The results show that, under compressive strain, the complex permittivity decreased slightly because of the breakdown of the original conductive network, whereas the complex permeability increased, but the enhancement mechanism was different.Inthe case of spherical CIPs/rubber composite, this was caused by the surface effect of the absorbents, and in the caseo ff laky CIPs/rubber compositebythe orientation of the flaky particles. As the compressive strain was applied, the RL value and the absorbing band changed slightly with thickness of 1mmor2mm. As the applied strains decreasedthe thickness of the composites,the absorption band ( RL < -10 dB) broadened and the minimum RL decreased.C.

“…Recently, the Heusler-type Ni-Mn-In shape memory alloys have attracted considerable attention due to their multi-functionalities [1], such as large magnetocaloric effect (MCE) [2], large magnetic-field-induced strain (MFIS) [3,4], giant magnetoresistance effect [5,6], and high magnetothermal conductivity [7]. All of these properties originate from the magnetic field-induced structural transformation from a high temperature high symmetry cubic structure (ferromagnetic austenite) to a low temperature orthorhombic structure (paramagnetic/antiferromagnetic martensite) with lesser crystal symmetry [8][9][10][11], which offers the possibility of application in high-performance actuators [12], environmentfriendly magnetic refrigerators [13], etc.…”

“…A large MCE usually occurs as the result of first-order magnetic transition in materials, such as Gd-Si-Ge [1], La-Fe-Si [2], and Fe-Mn-P-As [3,4]. To date, the large inverse MCE have been reported in Ni-Mn based Heulser alloys, such as Ni-Mn-Sn [5], Ni-Mn-In [6,7], and Ni-Mn-Sb [8], which undergoes a first order structure transition (martensitic transition) from a high-symmetry austenitic phase to a low-symmetry martensitic phase with an abrupt drop of magnetization. The large MCE has been studied in compounds doping with Si, Ga, Ge and Co in Sb site in Ni-Mn-Sb system [9][10][11][12][13].…”

The isothermal section of the Ni-Mn-Sb ternary system at 773 K was measured by means of 117 alloys which were analyzed by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), and electron probe microanalysis (EPMA) techniques. The existence of 7 binary compounds, namely NiMn, Mn 2 Sb, MnSb, NiSb 2 , NiSb, Ni 5 Sb 2 , Ni 3 Sb and 2 ternary compounds, namely Ni 2 MnSb and NiMnSb were confirmed for this isothermal section. The four binary compounds Ni 3 Sb (Cu 3 Ti structure, Pmmn space group), Ni 5 Sb 2 (Ni 5 Sb 2-type structure, C2 space group), NiSb 2 (FeS 2-type structure, Pnnm space group) and Mn 2 Sb (Cu 2 Sb-type structure, P4/nmm space group) in the binary systems Ni-Sb and Mn-Sb were stoichiometric compounds, the homogeneity ranges of which were negligible. However the five single phases in the Ni-Mn system and the two binary compounds MnSb and NiSb showed more or less homogeneity ranges formed by substitution of Mn and Sb for Ni atom. The Heusler compound μ (Ni 2 MnSb) has L21-type ordered structure with space group Fm-3m, a = 0.6017 nm. And the crystal structure for the Half-Heusler compound κ (NiMnSb) is C1b-type (F-43m) with a = 0.5961 nm. The approximate homogeneity ranges of the two ternary compounds μ and κ at 773 K were investigated.
