Title: Determining the vibrational entropy change in the giant magnetocaloric material ${LaFe}_{11.6} {Si}_{1.4}$ by nuclear resonant inelastic x-ray scattering

Abstract

Magnetocaloric $${\mathrm{LaFe}}_{13{-}x}{\mathrm{Si}}_{x}$$-based compounds belong to the outstanding materials with potential for efficient solid-state refrigeration. We have performed temperature-dependent $$^{57}\mathrm{Fe}$$ nuclear resonant inelastic x-ray scattering measurements (in a field $${{\mu}}_{0}H$$ of $${\sim}0.7$$ T) of the vibrational (phonon) density of states, VDOS, in $${\mathrm{LaFe}}_{11.6}{\mathrm{Si}}_{1.4}$$ across the metamagnetic isostructural first-order phase transition at $${T}_{C}{\sim}192$$ K from the low-temperature ferromagnetic (FM) to the high-temperature paramagnetic (PM) phase, in order to determine the change in thermodynamic properties of the Fe lattice at $${T}_{C}$$. The experimental results are compared with density-functional-theory-based first-principles calculations using the fixed-spin moment approach. Our combined experimental and theoretical results reveal distinct and abrupt changes in the VDOS of the Fe sublattice across $${T}_{C}$$, occurring within a small temperature interval of $$\mathrm{{\Delta}}T{\le}12$$ K around $${T}_{C}$$. This indicates that strong magnetoelastic coupling (at the atomic scale) is present up to $${T}_{C}$$, leading to a pronounced lattice softening (phonon redshift) in the PM phase. These changes originate from the itinerant electron magnetism associated with Fe and are correlated with distinct modifications in the Fe-partial electronic density of states $$D({E}_{F}$$) at the Fermi energy $${E}_{F}$$. From the experimental VDOS we can infer an abrupt increase (jump) in the Fe-partial vibrational entropy $$\mathrm{{\Delta}}{S}_{\mathrm{vib}}$$ of $$+6.9\pm{}2.6$$ J/(kg K) and in the vibrational specific heat $$\mathrm{{\Delta}}{C}_{\mathrm{vib}}$$ of $$+2.7\pm{}1.6$$ J/(kg K) upon heating. The increase in magnitude of the vibrational entropy $$|\mathrm{{\Delta}}{S}_{\mathrm{vib}}|=6.9$$ J/(kg K) of the Fe sublattice at $${T}_{C}$$ upon heating is substantial, if compared with the magnitude of the isothermal entropy change $$|\mathrm{{\Delta}}{S}_{\mathrm{iso}}|$$ of 14.2 J/(kg K) in a field change $$\mathrm{{\Delta}}B$$ from 0 to 1 T, as obtained from isothermal magnetization measurements on our sample and using the Maxwell relation. Finally, we demonstrate that $$\mathrm{{\Delta}}{S}_{\mathrm{vib}}$$ obtained by nuclear resonant inelastic x-ray scattering is a sizable quantity and contributes directly and cooperatively to the total entropy change $$\mathrm{{\Delta}}{S}_{\mathrm{iso}}$$ at the phase transition of $${\mathrm{LaFe}}_{13{-}x}{\mathrm{Si}}_{x}$$.

Influence of hydrogenation on the vibrational density of states of magnetocaloric $LaFe_{11.4} Si_{1.6} H_{1.6}$

Journal Article Terwey, A. ; Gruner, M. E. ; Keune, W. ; ... - Physical Review B

We report on the impact of magnetoelastic coupling on the magnetocaloric properties of LaFe_11.4Si_1.6H_1.6 in terms of the vibrational (phonon) density of states (VDOS), which we determined with ⁵⁷Fe nuclear resonant inelastic x-ray scattering (NRIXS) measurements and with density functional theory (DFT) based first-principles calculations in the ferromagnetic (FM) low-temperature and paramagnetic (PM) high-temperature phase. In experiments and calculations, we observe pronounced differences in the shape of the Fe-partial VDOS between nonhydrogenated and hydrogenated samples. Furthermore, this shows that hydrogen not only shifts the temperature of the first-order phase transition, but also affects the elastic response of the Fe subsystemmore »« less

Element-resolved thermodynamics of magnetocaloric ${LaFe}_{13 - x} {Si}_{x}$

Journal Article Gruner, Markus E. ; Keune, Werner ; Cuenya, B. Roldan ; ... - Physical Review Letters

By combination of two independent approaches, nuclear resonant inelastic x-ray scattering and first-principles calculations in the framework of density functional theory, we demonstrate significant changes in the element-resolved vibrational density of states across the first-order transition from the ferromagnetic low temperature to the paramagnetic high temperature phase of LaFe_13-xSi_x. These changes originate from the itinerant electron metamagnetism associated with Fe and lead to a pronounced magneto-elastic softening despite the large volume decrease at the transition. As a result, the increase in lattice entropy associated with the Fe subsystem is significant and contributes cooperatively with the magnetic and electronic entropy changesmore »« less

Critical behavior and magnetocaloric effect in ${Mn}_{3} {Si}_{2} {Te}_{6}$

Journal Article Liu, Yu ; Petrovic, C. - Physical Review B

Here, the critical properties and magnetocaloric effect of semiconducting ferrimagnet Mn₃Si₂Te₆ single crystals have been investigated by bulk magnetization and heat capacity around T_c. Critical exponents β = 0.41 ± 0.01 with a critical temperature T_c = 74.18 ± 0.08 K and γ = 1.21 ± 0.02 with T_c = 74.35 ± 0.05 K are deduced by the Kouvel-Fisher plot, whereas δ = 4.29 ± 0.05 (3.40 ± 0.02) is obtained by a critical isotherm analysis at T = 74(75)K. The magnetic exchange distance is found to decay as J (r) ≈ r^-4.79, which lies between the mean-field and 3D Heisenberg models. Moreover, the magnetic entropy change -ΔS_M features a maximum at T_c, i.e., -ΔSmore »« less
