They are experts in their fields vs They are experts on their fields

Both phrases are correct, but they are used in slightly different contexts. 'They are experts in their fields' is the more common expression, indicating that they have deep knowledge and skill within their specific areas. On the other hand, 'they are experts on their fields' can also be used, but it implies a slightly different focus, suggesting expertise regarding actual fields themselves (such as football fields or meadows) rather than within them.
