Hard magnetic properties of Mn-Ga melt-spun ribbons

New hard magnetic phase in Mn–Ga–Al system alloys

“…Mn-based compounds, such as the Mn-Ga, Mn-Bi, and Mn-Al magnets, have attracted attention as a possible alternative to rare-earth permanent-magnet materials because of their convenience [3][4][5][6][7][8][9]. Of these compounds, the Mn-Ga magnet is a relatively new material and its magnetic property has been intensively investigated in recent years [10][11][12][13][14][15][16]. We also reported the synthesis of a Mn-Ga magnet consisting of the D0 22 -type Mn 3 Ga phase by employing a melt-spinning technique when studying the Mn-based magnets [17].…”

High coercivity in Mn-Ga-Cu alloys

“…Bulk materials with the D0 22 -Mn 3 Ga phase have been produced, but their reported coercivity is not yet comparable to that of the D0 22 -Mn 3 Ga film. [21][22][23] In order to produce Mn-Ga magnets for practical applications, it is necessary to improve the coercivity of bulk D0 22 -Mn 3 Ga materials.…”

Phase Structure and Magnetic Properties of Mn70Ga30–xSnx ($x = 5$ –30) Alloy Ribbons

“…Compared with Ge, Sn is a cheaper element; it is of interest to study the effects of Sn substitution for Ga on phase structure Manuscript and magnetic properties in Mn-Ga-Sn system. In previous work, we reported the phase evolution, electric, and magnetic properties of the annealed Mn 60+x Ga 40−x (x = 0, 5, 10, 15) melt-spun ribbons [16]. In this paper, Mn 70 Ga 30−x Sn x (x = 5, 10, 15, 20, 30) ribbons were prepared using meltspinning and subsequently annealing.…”
