Magnetic field-induced narrow first-order and metamagnetic phase transitions of Nd₅Ge₃

We report on the magnetic behaviour of Nd5Ge3 by investigating through magnetization, neutron diffraction and muon spin relaxation measurements. Temperature dependent-magnetization, muon depolarization rate (lambda), initial asymmetry (A(0)) and the stretched exponent (beta) show a clear anomaly at the Neel temperature T-N similar to 54 K. However, the short-range correlated ferromagnetic interactions below T-N are inferred from the diffuse scattering mechanism as revealed by zero-field neutron diffraction data. Narrow first order phase transition is due to the competing interaction of a high temperature weak-antiferromagnetic and low temperature glassy states. Magnetic field-induced reentrant spin glass state from a magnetic glass state is observed, before it transforms to a ferromagnetic state. (c) 2024 Author(s).
