Generation of magnetic phase diagram of HoRu2Si2 using magnetocaloric effect

To get complete knowledge about the evolution of different magnetic phases on application of temperature and magnetic field magnetic, magnetotransport and magnetocaloric properties of HoRu2Si2 have been investigated from 2 to 100 K in magnetic fields ranging from 0 to 70 kOe in detail. The complex magnetic phase diagram of HoRu2Si2 has been generated by studying magnetocaloric effect (MCE). Three ordered phases have been observed. With lowering of temperature in the presence of lower magnetic field (<10kOe) two different types of ordered antiferromagnetic phases have been observed. Both of the phases show metamagnetic transition on application of external magnetic field greater than the required critical field. An efficient procedure to construct magnetic phase diagram using MCE has been described. The overlap of the data points obtained from the magnetization and magnetotransport data at the phase boundaries with those generated by MCE indicates the strength of this powerful technique.
