Possible quadrupole-order-driven commensurate-incommensurate phase transition in B20 CoGe

S. -H. Baek, V. A. Sidorov, A. V. Nikolaev +3

The B20-type cobalt germanide CoGe was investigated by measuring the specific heat, resistivity, and ${}^{59}$Co nuclear magnetic resonance (NMR). We observed a phase transition at $…
