  • Effect of magnetic field on microhardness of germanium 
    Makara, V.A.; Steblenko, L.P.; Kuryliuk, A.M.; Naumenko, S.M.; Kolchenko, Iu.L.; Kravchenko, V.M. (Functional Materials, 2007)
    Microhardness variations in germanium crystals caused by a weak constant magnetic field have been studied. It is fount that the magnetomechanical effect, that is relative change in microhardness, becomes relaxed in time. ...
  • Effect of weak magnetic field on structural arrangement of extrinsic oxygen atoms and mechanical properties of silicon monocrystals 
    Makara, V.A.; Steblenko, L.P.; Kolchenko, Yu.L.; Naumenko, S.M.; Lisovsky, I.P.; Mazunov, D.O.; Mokliak, Yu.Yu. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    IR spectroscopy study is indicative of the change in the relative concentration of interstitial oxygen in silicon monocrystals after their treatment by using the magnetic field. This is an evidence of a considerable effect ...
  • Modification of sintered iron properties by Y₂O₃ nanoparticles 
    Cherednyk, M.I.; Popov, O.Yu.; Chornobuk, S.V.; Totsky, I.M.; Semenko, M.P.; Boshko, O.I.; Tkachuk, V.Ja.; Slobodianyk, Y.V.; Naumenko, S.M.; Makara, V.A. (Functional Materials, 2016)
    Influence of Y₂O₃ nanoparticles on sintered iron structure and microhardness is investigated. Ferrite grain growth is shown to be slowed down by the clusters which cause altering the grain shape from needle-like to equiaxial ...
  • Relation between structure inhomogeneities and relaxation processes in excited silicon crystals 
    Makara, V.A.; Kolomiets, A.M.; Kolchenko, Yu.L.; Naumenko, S.M.; Rudenko, O.V.; Steblenko, L.P. (Functional Materials, 2004)
    The part played by electric current pulses in formation of residual electroplastic effect and the "electric memory" effect in dislocation-containing silicon crystals has been investigated. The character of the observed ...
  • Silicon crystal strength reduction due to magnetoresonance 
    Makara, V.A.; Pogorilyi, A.M.; Steblenko, L.P.; Kuryliuk, A.M.; Naumenko, S.M.; Kobzar, Yu.L.; Kravets, A.F.; Podyalovsky, D.I.; Matveeva, O.V. (Functional Materials, 2007)
    The magnetoresonance influence as well as the micrawave superhigh-frequency (SHF) magnetic field effect on the microhardness of silicon crystals has been studied. It is established that the action of SHF field results in ...
  • The relaxation of magnetomechanical effect in silicon crystals under cyclic magnetic treatment 
    Makara, V.A.; Steblenko, L.P.; Kuryliuk, A.M.; Kobzar, Iu.L.; Naumenko, S.M.; Krit, A.M.; Kravchenko, V.M. (Functional Materials, 2009)
    The experimental magnetic treatment conditions of silicon crystals in a weak (B = 0.17 T) magnetic field which provide a long-term stability of magnetomechanical effect (MME) have been investigated. It is established that ...
