Structural and magnetic properties of(Fe1−xMnx)

Abstract

Structural and magnetic properties of (Fe 1Ϫx Mn x ) 3 P compounds have been investigated by means of x-ray and neutron diffraction experiments, magnetization measurements, Mössbauer experiments, and first principles calculations. The Curie temperature of the system decreases linearly and rapidly with increasing Mn content. The zero temperature saturation magnetization, the local magnetic moments, as well as the hyperfine fields on the different metal positions of the system all decrease with increasing Mn content. The theoretical calculations, on the other hand, predict an increasing magnetic moment on the metal positions with increasing Mn content. This apparent discrepancy is discussed in the light of a good agreement between experimental and theoretical results for the Co-substituted sister compounds (Fe 1Ϫx Co x ) 3 P. PHYSICAL

Magnetostructural study of the (Mn,Fe)3(P,Si) system

“…The Mn 3−x Fe x P system maintains the same I4 tetragonal crystal structure for 0 < x < 1 [25,26] and again for 2.2 < x < 3 [24,26], approximately. In the gap between these two intervals an orthorhombic structure is reported [26].…”

“…Mn 3 P is an antiferromagnet with a T N of about 115 K and a magnetic moment of 1.69 B per Mn atom [24]. Fe 3 P on the other hand is a ferromagnet with a T C of about 700 K and a magnetic moment of 1.89 B per Fe atom [24].…”

Dependence of Magnetic Properties with Structural/Microstructural Parameters of Ball-milled Fe15Co2P3 Powder Mixture

“…In recent years, great attention has been given to the thermal stability of transition metal phosphides nanomaterials [22,23]. Others studies of Co2P encapsulated in N, Pdoped grapheme, CoMnP nanoparticles, nanostructured Fe92P8 and Fe-Co, MnFeP1-yAsy, (Fe1-xMnx)3P, Li-Fe-P and FeP alloys report a robust catalytic activity [24,25], interesting magnetic [26,27], electronic and mechanical properties [28,29], and a good storage energy capacity [30,31]. These properties can be altered by changing the chemical composition, type of crystal structure, and grain size.…”

Thin Films of (Fe1–xCox)3P and Fe3(P1–xTex) from the Co-Decomposition of Organometallic Precursors by MOCVD

“…Research in transition-metal phosphide materials has burgeoned in recent years with reports of robust catalytic activity, [1][2][3][4][5][6][7][8] magnetic properties, [9][10][11] and energy storage capacity. [12][13][14] The similarity of their binary solid crystal structures gives the flexibility of designing materials by introducing a third element.…”

“…[15][16][17] The magnetic properties of the system (Fe 1-x M x ) 3 P have previously been manipulated by varying the dopant M (M = Mn, Co, Cr, and Ni) by conventional solid state synthesis. 11,[18][19][20] However, the formation of these compounds in a single, pure phase remains challenging.…”
