Infrared absorption and Zeeman effect in Nd3+ doped YVO4

Abstract Low temperature infrared transmission studies of Nd3+ doped YVO4 were performed, under a magnetic field B ⊥c, in the 1800–8000 cm−1 range of the 4 I 9/2 → 4 I 11/2 , 4 I 13/2 , and 4 I 15/2 Nd3+ crystal-field transitions. Good agreement is obtained between the experimental and calculated g-factors. Frequencies of the satellites in the 4 I 9/2 → 4 F 3/2 transitions of the Nd3+ isolated ion confirm the presence of ferromagnetic interactions between pairs of coupled Nd3+ ions that lift the Kramers doublet degeneracies of their ground state and excited multiplets.
