    • Ferroelasticity, anelasticity and magnetoelastic relaxation in Co-doped iron pnictide: Ba(Fe0.957Co0.043)2As2 

      Carpenter, Michael A.; Evans, Donald; Schiemer, J. A.; Wolf, Thomas; Adelmann, P.; Böhmer, A. E.; Meingast, C.; Dutton, S. E.; Mukherjee, P.; Howard, Christopher J. (Journal article; Peer reviewed, 2019)
      The hypothesis that strain has a permeating influence on ferroelastic, magnetic and superconducting transitions in 122 iron pnictides has been tested by investigating variations of the elastic and anelastic properties of ...

    • Strain relaxation behaviour of vortices in a multiferroic superconductor 

      Evans, Donald; Schiemer, J. A.; Wolf, T.; Adelmann, P.; Böhmer, A. E.; Meingast, C.; Dutton, S. E.; Mukherjee, P.; Hsu, Y.-T.; Carpenter, Michael A. (Journal article; Peer reviewed, 2019)
      The elastic and anelastic properties of a single crystal of Co-doped pnictide Ba(Fe0.957Co0.043)2As2 have been determined by resonant ultrasound spectroscopy in the frequency range 10–500 kHz, both as a function of temperature ...

    • Strain relaxation dynamics of multiferroic orthorhombic manganites 

      Carpenter, Michael A.; Pesquera, David; O'Flynn, Dan; Balakrishnan, Geetha; Mufti, Nandang; Nugroho, A A; Palstra, Thomas T M; Mihalik, Marian; Mihalik, Matus; Zentkova, Maria; Almeida, Abilio; Moreira, Joaquim Agostinho Agostinho; Vilarinho, Rui; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2020)
      Resonant ultrasound spectroscopy has been used to characterise strain coupling and relaxation behavior associated with magnetic/magnetoelectric phase transitions in GdMnO3, TbMnO3 and TbMn0.98Fe0.02O3 through their influence ...
