Abstract

The temperature-dependent magnetization, lattice, and transport properties of Mn₃Sn_1-xGe_xC (0 ≤ x ≤ 0.5) compounds are systematically investigated. The Mn-Mn atomic distance decreases as Ge content is increased, and the transition temperature from ferromagnetic (or ferrimagnetic) to paramagnetic state decreases too. Mn₃SnC has a large magnetovolume effect (MVE). However, Ge-doping in Mn₃SnC gradually reduces the MVE, till the MVE disappears. Whether there is an abnormal lattice change or not, there always exists an anomalous increase in resistivity near the magnetic phase transition point with decreasing temperature.
