abstract = {The thermal expansion of La0.5Sr0.5Co0.25Fe0.75O3 (LSCF55)
is investigated both by first principles phonon calculations
combined with the quasi‐harmonic approximation (QHA) and
by experimental approaches. Within the framework of the QHA,
the volumetric thermal expansion coefficient of rhombohedral
LSCF55 is calculated as αV,GGA = 50.34 × 10−6 K−1. For
comparison, the lattice expansion and the volume expansion
of LSCF55 grain are measured by in situ high‐temperature
X‐ray diffractometer (HT‐XRD). An anisotropic thermal
expansion of rhombohedral LSCF55 with αa,hex = 10.89 ×
10−6 K−1 and αc,hex = 21.18 × 10−6 K−1 is
obtained. The volumetric thermal expansion coefficient is
measured as αV,HT‐XRD = 43.17 × 10−6 K−1. In
addition, the effectively isotropic expansion coefficients
of a polycrystalline LSCF55 bar specimen are measured using
a vertical high‐performance thermo‐mechanical analyzer
and yield αl,bar specimen = 17.37 × 10−6 K−1 and
αV,bar specimen = 52.11 × 10−6 K−1.},
