Critical phenomenon and phase diagram of Mn-intercalated layered MnNb 3 S 6
The magnetization of Mn-intercalated layered MnNb S single crystal has been systematically investigated. The angle-dependent magnetization ([Formula: see text], [Formula: see text], and [Formula: see text]) displays that the magnetization of MnNb S with [Formula: see text] is much stronger than that...

Zusammenfassung: | The magnetization of Mn-intercalated layered MnNb
S
single crystal has been systematically investigated. The angle-dependent magnetization ([Formula: see text], [Formula: see text], and [Formula: see text]) displays that the magnetization of MnNb
S
with [Formula: see text] is much stronger than that with H//c, but no magnetic anisotropy within the ab-plane. In addition, a field-induced magnetic phase transition is found when [Formula: see text]. The investigation of the critical behavior gives the critical exponents [Formula: see text], [Formula: see text], and [Formula: see text] with [Formula: see text] K, which belong to the universality class of three-dimensional Heisenberg model. The critical behavior and exponents indicate that the magnetic coupling in MnNb
S
is of an isotropic short-range type. Based on universality scaling, the H - T phase diagram with [Formula: see text] is constructed. The magnetic behaviors and phase diagram of MnNb
S
are analogous to those of CrNb
S
which exhibits a chiral magnetic soliton lattice. |
