Temp data is capable of handling single subsequent request. Hence, value gone after refresh the page. To mitigate this issue, we can use Session variable also in this case. Try below:

public ActionResult Index(Person _person)
{
    Session["personNickName"] = _person.nickName;
    return RedirectToAction("profile", "person");
}

And in "profile" actionmethod:

public ActionResult profile()
{
    Person nickName=(Person)Session["personNickName"];
    if(nickName !=null)
    {
    //Do the logic with the nickName
    }
}
