Helimagnetism in MnP-type compounds: MnP, FeP, CrAs and CrAs1−xSbx mixed crystals

Electronic structure and magnetic properties in CrX (XP, As and Sb)

“…3. The magnetic moment/Cr atom is obtained to be 2.7 m B , which agrees well with the experimental values 2.7 [3] and 3.0 m B [2]. It is noted that the d electrons polarize strongly in CrSb.…”

“…It is noted that the significant decrease of atomic radius of the pnicogen atoms in the order of Sb, As, and P brings about the remarkable decrease of a-axis as well as the orthorhombic deformation as X changes from Sb to P, as seen in Table 1. Magnetic properties of CrX compounds depend also on X: CrSb shows a collinear antiferromagnetic order with the Cr magnetic moment of about 3.0 m B [2,3]; CrAs shows a double spiral magnetic order [4] with the magnetic moment/Cr atom of 1.7 m B , about a half of that in CrSb; CrP is a paramagnet with a magnetic susceptibility very weakly dependent on temperature [5]. It is also noted that the magnetic ordering of CrAs disappears by only a few per cent P-substitution for As in CrAs [6].…”

Chemical Routes for Production of Transition‐Metal Phosphides on the Nanoscale: Implications for Advanced Magnetic and Catalytic Materials

“…Finally, we suspect the behavior observed for nanoscale MnP and FeP is likely to be characteristic of other helimagnetic phases that adopt the MnP structure-type (e.g., CrAs), [32] a subject that we will continue to investigate.…”

Magnetic and structural properties of pseudo-binary compounds CrAs1−P

“…There have been reports for magnetic properties of pseudo-binary Cr pnictides with the MnP-type crystal structure: CrAs 1−x P x by Selte et al [5], CrAs 0.98 Sb 0.02 and Cr 1−x M x As (M = Ti, Fe, Co, Ni) by Suzuki and Ido [6,7], Cr 1−x V x As by Selte et al [8], and CrAs 1−x Sb x by Kamigaki et al [11], Yoshida et al [10], and Suzuki and Ido [9]. In all the above reports, their magnetic properties are discussed in the relation with the crystal parameters in order to make clear the origin of their antiferromagnetism.…”
