Generalizations of the Weiss Molecular Field Theory of Antiferromagnetism* 

 P. W. Anderson.i Fhys. Rev., v. 79, pp. 705-710, Aug. 15, 1950. 



Abstract — A Weiss field calculation has been carried out for antiferro- 

 magnetism in more complicated structures than the usual calculation allows 

 and has been shown to give results more detailed and more consistent with 

 experimental evidence on the magnetic properties of such structures than 

 does the simpler theory.

Recording Fluxmeter of High Accuracy and Sensitivity.* P. P. Cioffi.^ 

 Rev. Sci. Instruments, v. 21, pp. 624-628, July 1950. 



Abstract — A recording fluxmeter has been developed which employs 

 one or two integrators and a double element L and N Speedomax recorder 

 for tracing magnetization curves directly on standard coordinate paper. 

 The response of the recorder pen drive mechanism is proportional to the 

 flux density, B, and is controlled by the B integrator. The response of the 

 paper drive mechanism is proportional to the magnetizing force, H, and is 

 controlled either by the magnetizing current, when the specimen is in the 

 form of a ring, or by the H integrator when the specimen is in the form of 

 a bar. Ayrton shunt networks provide flexible B and H scale adjustments. 

 High accuracy and sensitivity are obtained by minimizing the causes 

 of drift. At maximum sensitivity, four interlinkages give a deflection of 

 one mm, 



Young^s Modulus and Its Temperature Dependence in 36 to 52 pet Nickel- 

 Iron Alloys.* M. E. Fine' and W. C. Ellis.^ //. Metals, v. 188, pp. 1120- 

 1125, Sept. 1950. 



Abstract — Young's modulus and its temperature coefficient in 36 to 

 52 pet Ni-Fe alloys depend upon composition and also the straining-anneal- 

 ing history. Alloys near 42.5 pet Ni, when worked cold and then annealed 

 at 400° or 600°C, have nearly zero mean thermoelastic coefficients between 

 — 50° and 100°C. A discussion of the theory is given.
