“…The observed anomalies are associated with the spin reorientation phase transition. The reorientation starts at about 160 K, where slope of c ac (T) curve changes, and ends at about 220 K, namely from the onset of the spin reorientation to c-axis at 220 K. Now, consider the special case of studied sample where the angle between M s and the tetragonal c-axis is 53 in degree about T = 160 K [7]. So, the value of C′ can be obtained via Eq.…”

PACS 75.30.Fv The electrical resistivity, r, and temperature derivative of resistivity (d /dT) of polycrystalline NdFe 11 Ti are investigated. The resistivity exhibits an anomalous behavior at about 160 K and 220 K. These anomalies attributed to spin reorientation phenomena originate from two magnetic phase transition. A modified theoretical model for electrical resistivity, r and dr/dT, behavior in the spin reorientation temperature (T SR ) region is presented. The results suggest that the average magnetic moment at T SR1 ~ 160 K is aligned along a cone angle and at T SR2 ~ 220 K along c-axis. The temperature dependence of ac-susceptibility, c ac (T), is presented. The results show the existence of the spin reorientation related to a magnetic phase transition.

“…Since the Nd-Fe-B permanent magnets with high performance were discovered many efforts have been made to explore novel rare earth-transition metal (R-T) intermetallic compounds and investigate their intrinsic magnetic properties [1][2][3][4][5][6][7]. Among the novel R-T intermetallic compounds, R 2 Fe 17 intermetallic compounds possess higher magnetization and have been receiving considerable attentions for their potential applications as permanent magnets [8][9][10].…”
