Title: Physical properties of the layered $$\mathcal{f}$$-electron van der Waals magnet Ce2Te5

Journal Article · · Physical Review Materials

Here. we report a detailed study of the magnetic, transport, and thermodynamic properties of Ce2Te5 single crystals, a layered $$\mathcal{f}$$-electron van der Waals magnet. Four consecutive transitions at ~5.2, 2.1, 0.9, and 0.4 K were observed in the ac-plane electrical resistivity $$\rho(T)$$, which were further confirmed in specific heat $$C_\text{p}(T)$$ measurements. Analysis of the magnetic susceptibility $$\chi(T)$$, the magnetic-field variation of $$\rho(T)$$, and the increase of the first transition temperature ($$T_c$$ ~ 5.2 K) with applied magnetic field indicates ferromagnetic order, while the decrease of the other transitions with field suggests different states with dominant antiferromagnetic interactions below $$T_2$$ ~ 2.1 K, $$T_3$$ ~ 0.9 K, and $$T_4$$ = 0.4 K. Critical behavior analysis around Tc that gives critical exponents $$\beta$$ = 0.31(2), $$\gamma$$ = 0.99(2), $$\delta$$ = 4.46(1), and $$T_c$$ = 5.32(1) K indicates that Ce2Te5 shows a three-dimensional magnetic critical behavior. Moreover, the Hall resistivity ρxy indicates that Ce2Te5 is a multiband system with a relatively high electron mobility ~2900 cm2 V–1 s–1 near $$T_c$$, providing further opportunities for future device applications.
