The Stoner–Wohlfarth (SW) model was calculated for the anisotropic case, by assuming crystallographical texture distributions as Gaussian, Lorentzian and cos n (alpha). All these distributions were tested and both Gaussian and cos n (alpha) give similar results for Mr/Ms above 0.8. However, the use of cosn (alpha) makes it easier to find analytical expressions representing texture.The Lorentzian distribution is a suitable choice for not wel laligned magnets, or magnets with a high fraction of misaligned grains. It is discussed how to obtain the alignment degree Mr/Ms directly from two measurements of magnetic remanence at the transverse and parallel directions to the alignment direction of the magnet .It is demonstrated that even the wel laligned magnets with Mr/Ms=0.96 present coercive field of 60–70% of the anisotropy field, depending on the chosen distribution.The anisotropic SW model was used for discussing hysteresis squareness. Improving the crystalographical texture, the loop squareness also increases. [less ▲]

The construction and characterization of static magnetic density flux and gradient standards by using permanent magnets is presented. In the first case, the field homogeneity is high enough to be measured by a nuclear magnetic resonance magnetometer, confirming the traceability of the standard. In the second case, a gradient standard is shown. The experimental results obtained by Hall probes are in agreement with theoretical calculations. Designing considerations about materials choice and mounting are also addressed. [less ▲]

The specific absorption rate (SAR) concept of hyperthermia ferrofluids is discussed. It is first suggested that SAR can be characterized at the steady state condition, taking into account the heating flow mechanism from the ferrofluid to the external environment. The temperature dependence of SAR is then addressed, indicating that the influence arises from both magnetic susceptibility and relaxation time of the system. At last, a single equation able to express the temperature versus time profile of a ferrofluid, when SAR is virtually temperature independent, is proposed up to the equilibrium condition. [less ▲]

The influence of the densification step, performed by uniaxial pressing at room temperature, on the coercivity of NdFeB bonded magnets has been analyzed. The mass density does not play any role on of non-cured magnets prepared by the mentioned method. Due to the brittle and intergranular character of the Nd Fe B-based phase fracture, the nano-sized grains are not affected or the modification is negligible, which maintains unchanged. After curing, the intrinsic coercivity of themagnets is reduced as a function of the compaction pressure increase. [less ▲]
