The Earth's inner core is molten (liquid) iron.
Is there such a thing as an outer core?

The outter core is liquid. The inner core is solid.

The inner most core is solid iron core and is surrounded by a liquid ironrich core.

Inner core:
It is 3,200 - 3,960 miles (5,150-6,370 km) below the earth's surface and mainly consists of iron, nickel and some lighter elements (probably sulphur, carbon, oxygen, silicon and potassium. The temperature in the inner core is about 9032 - 10832 ºF (5000-6000 ºC). Because of the high pressure, the core is solid. The average density of the core is about 15g/cm³.
Outer core:
The outer core is at 1,800 - 3,200 miles (2,890-5,150 km) below the earth's surface. The outer core is liquid and mainly consists of iron, some nickel and about 10% sulphur and oxygen. The temperature in the outer core is about 7200 - 9032 ºF (4000-5000ºC). The density of the outer core is between the 10g/cm³ and 12,3g/cm³. The outer core and inner core together cause the earth's magnetism.
I found this info on the link below...so I copied it for you.

Outter.
The inner core is solid iron.
