Anisotropic magnetic property, magnetostriction, and giant magnetocaloric effect with plateau behavior in TbMn(2)Ge(2) single crystal

The ternary RMn(2)Ge(2) (R = rare earth) intermetallic compounds have attracted great attention due to their interesting magnetic behaviors and magnetotransport responses. Here, we reported our observation of anisotropic magnetic property, magnetostriction, and magnetocaloric effect (MCE) in TbMn(2)...

description The ternary RMn(2)Ge(2) (R = rare earth) intermetallic compounds have attracted great attention due to their interesting magnetic behaviors and magnetotransport responses. Here, we reported our observation of anisotropic magnetic property, magnetostriction, and magnetocaloric effect (MCE) in TbMn(2)Ge(2) single crystal. Below the transition temperature of Tb magnetic sublattices ([Formula: see text]  ~ 95 K), strong Ising-like magnetocrystalline anisotropy is observed with an out-of-plane ferromagnetic moments 5.98 μ(B)/f.u. along the easy c axis, which is two orders of magnitude larger than that of field along a axis. Above [Formula: see text] , a field-induced metamagnetic transition is observed from the spin-flip of Mn sublattices. During this transition, remarkable magnetostriction effect is observed, indicating of strong spin–lattice coupling. The responses of Tb and Mn sublattices to the magnetic field generate a giant magnetic entropy change ([Formula: see text]) and large values of relative cooling power (RCP) and temperature-averaged entropy change (TEC). The calculated maximum magnetic entropy change ([Formula: see text]), RCP, and TEC(10) with magnetic field change of 7 T along c axis reach 24.02 J kg(−1) K(−1), 378.4 J kg(−1), and 21.39 J kg(−1) K(−1) near [Formula: see text] , which is the largest among RMn(2)Ge(2) families. More importantly, this giant MCE shows plateau behavior with wide window temperatures from 93 to 108 K, making it be an attractive candidate for magnetic refrigeration applications.
