Abstract
The temperature dependences of the resistance R(T) and the singular part of near the critical regime and in the presence of magnetic fields H (0-5 T) are presented in this paper. The measurements were carried out using a novel technique from which ~~i)~ can be determined directly. This quantity, being related to the transport coefficient ( j~i, is directly connected to the specific heat behavior near the phase transition. The high accuracy of our experimental data allows us to compare the critical exponents deduced from our previous mea- surements in zero field (H = 0 T) and those predicted by several models of the renormal12ation group theory. We present a complete phase diagram for a single crystal of erbium oriented along the c-axis- This constitutes the first systematic study of field-induced magnetic phase transitions using the magnetoresistance R(T, NJ and its derivative ~ji( ~ near the critical points.
