The electrical conductivity and pyroelectrical properties of ferric acetylacetone single crystal
Acta Physica Hungarica - Tập 60 - Trang 107-112 - 1986
N. M. Molokhia
The dielectric constant, the electrical conductivity and the pyroelectric behaviour of ferric acetylacetone Fe(ac.ac)3 single crystal have been measured as a function of temperature from 20 to 140 °C. The measurements along theb-axis show a peak value in the dielectric constant at 82 °C, while no peaks were recorded along the other axes. This anomaly is described as due to a phase transition.

A theory of massive photons and monopoles
Acta Physica Hungarica - Tập 67 - Trang 359-362 - 1990
G. Callegari, P. Fortini, D. Tartari
A unified theory of massive photons and monopoles is proposed and compared with the measurement of the magnetic field of the earth.
Finite element analysis of process control and operating limits in edge-defined film-fed growth (EFG) of silicon and sapphire ribbons: A review
Acta Physica Hungarica - - 1985
J.P. Kalejs, Hisham Ettouney, Robert A. Brown
The origin of Sm ion intermediate valence state in SmB6
Acta Physica Hungarica - Tập 75 Số 1-4 - Trang 221-225 - 1994
P. A. Alekseev, V. N. Lazukov, I. P. Sadikov
Effect of perturbation to the thermodynamic system
Acta Physica Hungarica - Tập 64 - Trang 379-384 - 1988
P. Samu
According to the Le Chatelier’s principle the spontaneous processes induced by a deviation from equilibrium are in a direction to restore the system to equilibrium. We give this principle in detailed and explicit form.
Radiation stimulated annealing of structural defects in layer structures based on Si and III–V compounds
Acta Physica Hungarica - Tập 59 Số 3-4 - Trang 327-332 - 1986
O. Yu. Borkovskaya, N. L. Dmitruk, Vasilij Y. Kiblik, V. G. Litovchenko, R. O. Litvinov
Electronic stopping power for different elements and inelastic energy loss in collision cascades
Acta Physica Hungarica - - 1985
I. Nágy, J. László, J. Giber
Ab initio calculations of polarizabilities of small molecules with Gauss-type function depending on perturbation
Acta Physica Hungarica - Tập 70 - Trang 299-316 - 1991
A. Bolotin, V. Rossikhin, E. Voronkov
An analytical method to determine polarizability tensor components for small molecules with closed shells is suggested. The dependence of initial basis set of Gauss-type functions on the perturbation parameter is taken into account within the framework of uncoupled variant of Hartree-Fock-Roothaan perturbation theory. The capabilities of developed approach are shown by the calculations of polariza...... hiện toàn bộ
Applications of dynamic neutron and gamma radiography at the Budapest research reactor
Acta Physica Hungarica - Tập 75 - Trang 227-230 - 1994
M. Balaskó, E. Sváb, I. Cserháti, F. Ozsvári, J. Oláh
Dynamic neutron and gamma radiography equipment (DNGR) has been installed at the Budapest research reactor. DNGR is used as non-destructive testing method for research and development of products for various companies. Investigations have been performed on absorption and compression type refrigerators which provide useful information for engineering and development work.
