We report on the temperature dependence of magnetization

(M)

and resistivity

(ρ)

{La}_{1 - x} {Sr}_{x} {CoO}_{3}

(

x = 0.10

and 0.33) single crystals. For

x = 0.10

, the temperature dependence of field-cooled magnetization

(M_{FC})

and zero-field-cooled magnetization

(M_{ZFC})

are similar to that expected for a canonical spin-glass system. The thermal response of

M_{ZFC}

for

x = 0.33

indicates a glassy ferromagnetic state. We observe that the ferromagnetic transition temperature

T_{C}

decreases and

ρ

increases rapidly with increasing pressure

(P)

for the metallic sample

(x = 0.33)

while the dependence of

ρ

P

for the insulating sample

(x = 0.10)

is quite complicated; the pressure coefficient of resistivity

(d ρ / d T)

is sensitive to temperature and applied pressure due to the strong interplay between the pressure-induced band broadening and spin-state transition phenomenon.

d ρ / d T

is large and negative at low-pressure and low-temperature regimes while small and positive at high pressures

(P > 5.4 GPa)

and high temperatures

(T > 110 K)
