The design and construction of a powerful electromagnet, and its application to magnetic measurements of the alloy MnA1C Kidson, Geoffrey Victor
An electromagnet capable of producing a magnetic field intensity of greater than 21,600 gauss in a gap of one inch and over an area of 3.14 square inches has been designed and constructed. The structure of the ternary alloy of approximate composition Mn₆ₒAl₂ₒC₂ₒ has been investigated by X-ray methods, and shown to have an ordered perovskite structure, with aₒ = 3,865 A⁰. The effective magnetic moment pit manganese atom was measured, using the electromagnet, and a torsion balance method. The value of the magnetic moment at zero degrees Kelvin was found to be 1.2 Bohr magnetons per manganese atom.
