Low temperature magnetic transitions of single crystal HoBi

•We have successfully synthesized high quality single crystals of HoBi using the excess flux method.•The rich low temperature behavior of HoBi is observed showing multiple magnetic transitions.•We were able to build a field-temperature phase diagram characterizing the low temperature behavior of the system.

We present resistivity, specific heat and magnetization measurements in high quality single crystals of HoBi, with a residual resistivity ratio of 126. We find, from the temperature and field dependence of the magnetization, an antiferromagnetic transition at 5.7 K, which evolves, under magnetic fields, into a series of up to five metamagnetic phases.
