Magnetic structure of NdB6

Single-crystalline LaxNd1−xB6 nanowires: synthesis, characterization and field emission performance

“…It can be seen that no impurity peaks were detected, which suggests the high purity of the synthesized products. The lattice parameter of La x Nd 1Àx B 6 is 4.142(5) Å, which is right between the standard lattice constants of LaB 6 (4.155 Å) 19 and NdB 6 (4.128 Å) 20 , which complies well with Vegard's law. 2a, the magnification of the strongest peak of the La x Nd 1Àx B 6 nanowires is right between the standard patterns peaks of LaB 6 and NdB 6 because of the different atom sizes of La and Nd.…”

“…The most common is antiferromagnetic (AF) ordering through the Ruderman-KittelKasuya-Yosida (RKKY) exchange interaction, which is strongly influenced by crystal field effects, as is seen in NdB 6 . This compound orders in an A-type collinear antiferromagnetic (AF) structure below T N ≈ 8 K. 2 The ground state of the Nd +3 ions (J = 9/2) is split in a cubic crystal field into two Γ 8 quartets and a Γ 6 doublet. 3,4 The first excited energy is approximately 135 K above the ground Γ 2 8 state, and the nearest Γ 6 excited doublet lies at 278 K. [3][4][5] A competition between ferro-quadrupolar 6 and crystalline-electric field 4 (CEF) interactions gives rise to a low-field magnetic anisotropy in NdB 6 which is much weaker than the isotropic magnetic exchange interaction.…”

Point-Contact Spectroscopy of Crystalline Electric Field of Heterocontacts PrB6and NdB6with Pt

“…In magnetically ordered phase we have seen another 2 maxima at ≈ 22 and ≈ 31 mV which are less pronounced in the paramagnetic state (due to thermal smearing of PC spectra). Taking into account the phonon point-contact spectra of LaB 6 [9] we conclude that this structure is due to the interaction of conduction electrons with phonons in NdB 6 .…”

“…NdB 6 is interesting due to its complicated magnetic transport properties, namely the anomalous large variation of the Hall coefficient in the neighborhood of critical temperature [5]. NdB 6 orders in an A-type collinear antiferromagnetic structure below T N ≈ 8 K [6]. The ground state of the Nd 3+ ions (J = 9/2) in crystalline electric field is the Γ (267) and doublet Γ 6 .…”
