Abstract

= 13 and T-N = 21 K. The paramagnetic Curie temperature of Tm5Ge4 is positive (theta(p) = 16 K), and the effective magnetic moment (p(eff) = 7.4 mu(B)/Tm) is in good agreement with the theoretical value of 7.56 mu(B)/Tm3+. The ac susceptibility of Tm5Ge4 shows obvious frequency dependence behaviors suggesting the existence of a ferromagnetic cluster in the antiferromagnetic substance. According to the magnetic hysteresis loop, the intrinsic coercivity of Tm5Ge4 is 2616 Oe at 2 K. Tm5Ge4 exhibits an oscillating magnetocaloric effect owing to a metamagnetic-like transformation induced by a critical magnetic field below 21 K.
