    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: This article presents a simple, lab scale, vacuum furnace design that features good temperature stability, rapid temperature response, and high-vacuum and high-temperature capabilities. The furnace was developed for applications such as in situ electrical resistivity measurements, precise heat treatment of small samples, and complex heat treatments.

    Improved furnace temperature control for the PARC vibrating sample magnetometer (1993)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 64 (1993), S. 1365-1366 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: Temperature control of furnaces to be used with the PARC vibrating sample magnetometer can be greatly improved if a separate temperature controller is utilized. A control circuit that allows easy temperature programming and ramping is described, as well as sample holder modifications which permit accurate measurement of the sample temperature.

    Microstructure and magnetic properties of inert gas atomized rare earth permanent magnetic materials (1997)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 81 (1997), S. 1351-1357

    Notes: Several permanent magnet alloys based on the ternary Nd2Fe14B (2-14-1) composition have been prepared by inert gas atomization (IGA). The microstructure and magnetic properties of these alloys have been studied as a function of particle size, both before and after heat treatment. Different particle sizes have characteristic properties due to the differences in cooling rate experienced during solidification from the melt. These properties are also strongly dependent on the alloy composition due to the cooling rate's effect on the development of the phase structure; the use of rare earth rich compositions appears necessary to compensate for a generally inadequate cooling rate. After atomization, a brief heat treatment is necessary for the development of the optimal microstructure and magnetic properties, as seen from the hysteresis loop shape and improvements in key magnetic parameters (intrinsic coercivity Hci, remanence Br, and maximum energy product BHmax). By adjusting alloy compositions specifically for this process, magnetically isotropic powders with good magnetic properties can be obtained and opportunities for the achievement of better properties appear to be possible. © 1997 American Institute of Physics.

    Notes: [Auszug] The evidence for this is based on the following claims: (a) Injections of serum taken from partially hepatectomized rats stimulate mitoses in a normal rat, or accelerate regeneration in another partially hepatectomized rat25. These claims have, however, been denied68. (b) Partial hepatectomy in one ...
